Fetal Echo Ultrasound 😥

Cristina
So I went in for my 20 weeks anatomy ultrasound today and they didn't tell me anything was wrong with my baby but I am being sent out for a Fetal Echo Ultrasound. I am so nervous as it is still 4 weeks away and that something is wrong with my baby's heart. I am diabetic so my husband thinks that's why they are sending me for this test. Anyone ever have this test? Should I be worried?
